In contemporary societies, subjects and communities increasingly find themselves exposed to forces that exceed human mastery, oscillating between violence and call, closure and openness. This situation is marked by a growing sensitivity to what Hartmut Rosa has described as resonance: a transformative relation to the world grounded not in control but in responsive openness. In a context of epistemic fragmentation and the disarticulation of shared truth, affectivity and narratives emerge as privileged sites of resistance and concordance, revealing unexpected forms of coherence. This paper argues that Catholic theology, while experiencing a crisis of intelligibility and institutional authority, stands at a kairos: it can rediscover its public relevance by rearticulating itself as a resonant discipline. Drawing on Rosa and engaging critically Michel de Certeau's diagnosis of the "misery of theology," it proposes to understand theology as an articulation of the unavailable (theos) within the rigor of logos. Such a theology does not seek to master the real but remains exposed to it, discerning and articulating the resonances that traverse history. This perspective allows Catholic theology to hold together two essential dimensions of catholicity: fidelity to singular revelation and openness to universal resonance. Grounded in the incarnation, theology appears as a practice of mediation between singularity and commonality, enabling a renewed public discourse rooted not in domination but in responsive participation. In this way, Catholic theology can contribute to contemporary debates by offering not a closed system of truths, but a grammar for inhabiting the world in a mode of resonance, responsibility, and hope.
